LEATHER-GLASSING MACHINE.

SPECIFICATION formingpart of Letters Patent No. 672,903, dated April 30,1901.

Application filed December 8, 1900. Serial No. 38,386. (No'modeh) Theobjects of the present invention in-' clude improvements in variousfeatures of construction and arrangement whereby an apparatus isproduced which has proved in practice to be better able to withstand thesevere strains of constant use and on account of its superiority ofstructure producing much less.

noise than usual and being at once more durable and economical inoperation, as will appear from the following description and theaccompanying drawings, in which Figure 1 is a vertical side elevation. 2is an end View thereof.

In the drawings, A is a strong wooden beam constituting the base orsill. of the base a are strongly secured two uprights B O, which extendupward therefrom in par- Fig.

allel forwardly-inclined positions and are se-- cured at their upperends to opposite sides of the front end of whatI have termed theheadboard D. Near the forward end of the base A are secured a secondpair of uprights E F, which are similarly secured on opposite sides ofthe rear end of the head-board D. The two sets of uprights intersect,forming an exceedingly strong and rigid X-frame sustained upon the baseA and supporting the head-board D. The said uprights B (J EB aredesirably secured together at the points of intersection, and it isfurthermore pointed out that the frame is not quite symmetrical, sincethe feet of the forward uprights E F are set some dis tance back of thefront end of the sill A,

which carries the work-bed, while the upward ends of the opposite set ofuprights extend At the rear end forward and connect with the forward endof the head-board D'at a point beyond the support"of the working tool,which travels over the bed, as will appear, the object being to affordsufficient space for the work-bed and tool and to efficientl'y supportthe tool-carrying mechanism suspended from the front end of, the saidhead-board D.

At the forward end of the sill A is located the work-bed G. This bed isconstructed in the usual well-known manner and is suspended upon awooden spring 6, the opposite ends of which are supported upon adjustingscrews ff, which are sustained in the baseblocks 0 0 mounted uponthe forward portion of the base A. Upon and over the bed G moves theglassing-tool g, which is reciprocated back and forth upon the surfaceof the leather placed upon the bed G. The glassingetool g is supportedby the rocker H, connected therewith through a vertical member h,extending downward from the middle of the rocker, said member It beingstrengthened by front and rear diagonal braces h M, extending from theunder side of opposite ends of the rocker H and secured to the verticalconnecting-bar h. The rocker is adapted to be held up against and moveupon a rockertread I,which is removably secured to the under side. ofthe head-board D, so that it may be readily renewed when worn. Thehead-board D is stationary, being secured between the upper portions ofthe four uprights. Above the rear portion of the headboard D is secureda spring-board d, which is most conveniently pivoted upon a bolt J,between the upward extensions E F of. the upright braces E F, althoughseparate supports upon the rear end of the head-board D would answer thesame purpose. The springboard (1 extends parallel with the-head-board Dto a point beyond the vertical support of the rocker H, with which it isconnected by bars or straps K L, which are connected above thespring-board by bolt is and extend down and through suitable slots oropenings (not shown) in the head-board D to and are pivotally connectedwith the center of the rocker H by a through-bolt M. This connectionsustains the rocker vertically and the spring-board d will yield topermit movement of the rocker. Springs, preferably coil-springs 70 Z,are intel-posed between the under side of the springboard d and theupper side of the head-board D, said springs being of a tension designedto carry the weight of the rocker and attached parts without undulyimpeding their movement. In order to keep the rocker in position andprevent longitudinal movement thereof as a whole, the longitudinal staysO P are provided in the form of narrow bars of metal, which are pivotedat their forward ends upon the bolt Mthat is, upon the same axis as thevertical supports K L-and are similarly secured at their rear ends by abolt on passing through a block m, secured under the rear end of thehead-board, or by a bolt passing through the rear uprights E F, so thatsaid stays have suificient length to permit cramping, are parallel andhorizontal, and cooperate with the vertical straps K L. This is avaluable feature of improvement, as the tendency of the rocker to creepalong its tread is continuous and powerful and is effectually preventedby means of this construction, which is simple and eEective.

The tool 9 is carried in a suitable head N, which is pivotally securedat the lower end of the vertical bar 71, depending from the rocker. Thehead N is joined to the drivingwheel Q by connecting-rod n, which at itsrear is journaled upon a crank-pin q. The driving-wheel Q is sustainedupon shaft R, which is mounted in asuitable journal secured to thecross-pieces at one side of the machine and extending laterallytherefrom to a suitable rigid support S, mounted upon separate base a,and the said shaft is provided with the usual fast and loose pulleys rs.

In order to readily compensate for wear on the surface of the rockeragainst its tread I, the latter is removably attached to the under sideof the head-board and may be made of a strip of the most suitable woodfor the purpose and may be dilferent in that respect from thehead-board.

Having specifically described my improved machine and the constructionand arrangement thereof, it will be apparent that minor changes andmodifications may be made by any one skilled in the art without theexercise of invention.

Having described my invention, what I claim is 1. In a glassing-machine,the combination with the base, work-bed on forward end thereof, ahead-board extending over the base and bed, and supporting a rocker nearits front end and over the work-bed, two sets of inclined uprights, therear end of one set exrear of the work-bed and to the rear end of theheadboard.

2. In a glassing-machine, the combination with the base, work-bed onforward end thereof, a head-board extending over the base and bed andsupporting a rocker near its front end and over the work-bed, two setsof inclined uprights, the rear end of one set extending from the rear ofthe base tothe front end of the head-board beyond the center of movementof the rocker and vertically over the bed, the other set extending fromthe base at the rear of the Work-bed and to the rear end of thehead-board.

3. In a glassing-machine,'the combination with the base, work-bed,sustaining-frame, and the rigidly-supported head-board, of aspring-board spring sustained above the headboard, a rocker suspendedbelow the headboard, and vertical and lateral stays therefor, havingtheir downward ends united upon the axis upon which the rocker issuspended.

4. In a glassing-machine, the combination with a base, a work-bed on thefront end thereof, a head-board extending over said workbed,cross-pieces connecting same, a rocker depending from the head-board, aspringboard over the work-bed, springs between the board and the bed, apair of suspensionstraps connected to the spring and .pivotallyconnected to the rocker below the head-board, and a pair of longitudinalstays arranged one on each side of the rocker and pivotally connectedthereto on the same axis as the supporting-straps and suitably securedat their rear ends.

5. In a glassing-machine, the combination with a base, work-bed,head-board extending over the bed, a pair of inclined uprights securedto and extending from the rear end of the base to and secured to thefront end of the head-board, a second pair of uprights secured to thebase near the rear of the workbed and extending up to and secured to therear end of the work-bed and having extensions, a spring-board pivotedat its rear end to the extensions of the uprights, a rockerframe andpolishing mechanism, springs between the pivoted spring-board and astationary head-board, a pair of straps extending from the spring-boarddownwardly and pivotally attached to the rocker for suspending thesameand a pair of longitudinal stays pivoted upon theaxis of the verticalstraps and extending rearward to and secured to a part connected to therear end of the head-board.

6. In a glassing-machine, the combination with the base, the work-bed onthe forward end thereof, of a head-board suspended so as to extend overthe work-bed, a rocker-frame, glassing-tool, and driving connections arranged between the front end of the headboard and the work-bed, two setsof inclined uprights, the rear end of one set secured to and extendingfrom the rear of the base and secured to the front end of thehead-board, said uprights arranged one on each side of the rocker andattached mechanism, the other set secured to the base near the rear ofthe work-bed and extending up to and secured to the rear of thehead-board, the two sets of uprights intersecting and forming an openframework within which the operating mechanism is free to move.
